Streamside ecological percolation and pollution intercepting pool equipped with oxygen releasing material

Abstract

The invention relates to a streamside ecological percolation and pollution intercepting pool equipped with an oxygen releasing material. The pool comprises a pool body 4, and the bottom part of the pool body is provided with a draining pipeline 10; the pool body 4 is provided with a gravel layer 9, an earthwork cloth 8, a packing layer 7, and a water plant support 16 from bottom to top in order; the water plant support 16 supports water plants 6, the packing layer 7 comprises a first oxygen releasing material layer, a first anthracite and zeolite mixing layer for hanging activated sludge, a second oxygen releasing material layer, a second anthracite and zeolite mixing layer for hanging activated sludge, and a third anthracite and zeolite mixing layer for hanging microalgae from bottom to top. The product comprehensively utilizes interception and adsorption of filling materials, purification effects of water plant roots, biodegradation function of activated sludge and microalgae, oxygenreleasing and adsorbing capability of the oxygen releasing material for carrying out pollution intercepting of river banks, solving rainwater runoff pollution of river water body, reducing pollutionload of river due to entrance of non-point source pollution with good landscape effects, and improving surrounding environments.

Description

technical field

[0001] The invention relates to the field of rainwater runoff treatment in urban rivers, in particular to a riverside ecological infiltration sewage interception pond filled with oxygen-releasing materials. Background technique

[0002] With the effective control of point source pollution such as industrial wastewater and urban domestic sewage, non-point source pollution, especially agricultural non-point source pollution caused by agricultural production and living activities, has become an important source of water environment pollution. Rainfall runoff is the main natural cause of non-point source pollution. Rainstorm runoff scours the organic matter layer on the surface, bringing suspended particles, organic matter, nutrients, toxic substances and other pollutants into the receiving water body, polluting the receiving water body and generating impact loads on the water body. Due to the diversity of non-point source pollution sources and the complexity of...
